Application: kmix (3.9)
KDE Platform Version: 4.7.4 (4.7.4)

-- Information about the crash:
- What I was doing when the application crashed:
Started jack as well as QSynth, went to turn on my MIDI syntesizer (portatone PSR-S700) which was connected through USB, came back to find KMix crashed.

- Custom settings of the application:
Not sure if related but I've uninstalled Pulseaudio (which was installed by default, using Fedora 16).

-- Backtrace:
Application: KMix (kmix), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
